It's Too Hot For My iPhone!

iPhone Too Hot

I went to use my iPhone and pressed the home button, and this appears on my screen!  What the heck?  


The temperature outside was about 110 but I didn't know that my phone would complain.  Luckily it recovered and I was able to use it within about a minute.


Hmmm...I wonder if there is a too cold warning message also.


Has this ever happened to you?
